O.k. I thought I would start a new thread to keep things clean, as it seems there is no stopping the flood..
So here goes (for nostalgia's sake, per original thread):

Personally, I am purely looking into the problem as engineering enthusiast who wishes to understand how things work.

The idea of the mod is to create a relay closed loop that can be switched off and then on remotely, here is a high level outline of needs to be done:

Procedure:

1 – Remove the 10A ESC fuse from the front passenger fuse box (2nd fuse in the middle row).
2 – Insert the 10A ESC fuse in the MINI In-Line Fuse holder.
3 – Connect both red cables, from the remote control unit as well as the relay sockets to the MINI In-Line Fuse holder.
4 – Connect the In-Line Fuse holder male shielded Electrical Wire Terminal Spade Connector
5 – Connect the blue cable from the relay socket to the shielded Electrical Wire Terminal Spade Connector.
6 – Connect the two white cables from the relay socket and the remote control using either the optional splice harness or solder together and tape together using weather proof tape.
7 – Connect the three black cables (two from the remote and the one from the relay socket) to a single black cable that be connected to vehicle ground.
8 - Insert Fuse Socket Connector where the ESC fuse was removed.
9 - Connect the in-line fuse to right terminal (facing the engine which is the live terminal).
10 - Connect the blue cable from the relay socket (facing the away from the engine which is the ESC feed).

Thanks to everyone's assistance and for keeping the flame alive or all these years, and I propose that we update this thread going forward.

I am glad it worked out for you guys..
please post any issues that you may encounter, as well as your results so we can collectively keep track of how many people have implemented this mod in its latest incarnation ...

Because as far as I know, until the V8 ECU is cracked this is the best we have got...

Been here awhile...

my initial tests show that without any traction control It would appear the 2011 4.6 has an open rear diff. I don't have any visual confirmation yet but the feel especially on wet pavement was one wheel spin.

I am very glad for the assembled pic's that made things very easy. though I am curious in the write up you never mentioned the yellow wire coming off the plug, it looks as though you cut it off at the plug in the pic. I just taped mine up very well just in case I was mistaken

I just got everything wired up and installed and tested for proper operation (correct lights turn on/off on the dash). I'll have to wait to find some open space to act inappropriate which probably means this weekend.
